Ampware launched its Indiegogo campaign today for the CrankCase, which puts a literal crank right on your iPhone so that you can manually provide power in case of a dead battery. This iPhone 6 case uses a patent pending design, which includes a pop-up hand crank, built-in USB sync/charging cable and a second USB port for charging other accessories. The crank also doubles as a kickstand, as well.

According to the Indiegogo product page, CrankCase will provide 40 minutes of talk time after one minute of hand-cranking. Ampware states that it also has an output of 500mA to any attached device.
